Diagnostics messages and maintenance events

Diagnostics messages
A diagnostics message is generated for each diagnostics event and the DIAG LED on the
DI 16×24VDC HA flashes red or the MT LED lights up yellow.
In addition, channel-specific channel diagnostics are displayed through the corresponding
channel error/status LEDs.
The diagnostics messages can be read in the diagnostics buffer of the CPU, for example.
Diagnostic messages are assigned either channel-specific to an input or assigned as module
messages to all inputs. All channels are switched off for diagnostics messages that affect the
entire module. Only the corresponding digital input is affected by diagnostics messages, which
refer to individual channels.

Module Error is reported because the events occur
faster than they can be processed in the
system.
Module Firmware update is in progress or has
been canceled during the update.
The module does not read any process
values in this state.

conductors with a larger cross-
section
Connect the cable
● Disable diagnostics
● Connect encoder contact
with a 15 kΩ to 18 kΩ
resistor.
● Switch off wire break check
● Correct the parameter
assignment
● Check terminal block
● Check the supply voltage L

● Check terminal block
● Restart the firmware
update
● Wait for firmware update
